how to restore Corrupt 'word' files

I have been given a memory stick to take a look at that is suffering a corruption problem.

The System is Win XP Pro

I contains in the main folders of jpg. files which are OK and a folder of Word files that appear to have corrupted.

When attempting to open a word file it presents as a series of rows of squares- which I seem to recall can to happen to image files if opening in a non graphic program..
Any though on how to restore theses files to word will be much appreciasted.

It could have been corrupted when transferring to the flash drive but hopefully the original will still be on the main computer. Or you could try repair my word CLICK HERE I don't know if it will work but its worth a try.
